3. Production and quality of Sweet Grape tomato in response to foliar calcium fertilization
ABSTRACT In tomato, foliar application of calcium-based nutrient solutions is used to complement soil fertilization. However, knowledge regarding the factors that influence the effectiveness of foliar fertilizer applications remains incomplete. The objective of this study was to evaluate the efficiency foliar fertilization with calcium for improving producti

6. Potential Slow Release Fertilizers Based on K2MgSiO4 Obtained from Serpentinite
In this work, a potassium magnesium silicate mineral based on phase K2MgSiO4 was prepared from serpentinite rock and studied as a potential K and Mg slow-release fertilizer. The material was prepared by impregnation of serpentinite/KOH and calcination at 700 °C to produce K2MgSiO4 phase, olivine and forsterite. The release patterns of K and Mg in the stirre

7. Effects of limestone and organic fertilizer on cassava yield and on chemical and physical soil properties
ABSTRACT Cassava has a high yield potential that can be achieved with adequate liming and fertilization of the soil. The objective of this study was to evaluate the effect of organic fertilizer application, in association or not with liming, on yield and morphological characteristics of cassava roots and on chemical and physical properties of the soil. The e

8. Potential utilization of spent Agaricus bisporus mushroom substrate for seedling production and organic fertilizer in tomato cultivation
RESUMO A produção de Agaricus bisporus resulta em material residual significativo após seu cultivo. O substrato pós-cultivo do cogumelo (SMS), devido às suas propriedades físicas e conteúdo de nutrientes, tem um grande potencial para uso na agricultura. Nosso estudo avaliou a viabilidade do uso do SMS como substrato alternativo para a produção de mu

9. Tuber yield and economic result of ‘Atlantic’ potato in response to NPK fertilizer formulas
RESUMO A aplicação usual de altas doses do fertilizante NPK 4-14-8 nos sulcos de plantio da cultura da batata, independentemente da fertilidade do solo ou das necessidades nutricionais da cultivar, tornou-se um paradigma no Brasil. Contudo, a fórmula 4-14-8 nem sempre atende as necessidades da cultura e pode desequilibrar a disponibilidade de nutrientes n

12. Adubação nitrogenada e intervalos de colheita na produtividade e nutrição da erva-mate e em frações de carbono e nitrogênio do solo
Resumo Na erva-mate (Ilex paraguariensis) o principal produto colhido é composto por folhas (FO) e galhos finos (GF), resultando em elevada exportação de nutrientes, dentre eles o N. As informações técnico-científicas disponíveis para subsidiar uma recomendação da adubação nitrogenada racional são insuficientes, o que põe em risco a sustentabil
